ADJUSTABLE WINDOW-SHADE FIXTURE.

To QZZ whom it may concern:

Be it known that 1, JOHN H. Brssnrr, a citizen of the United States, anda resident of Dorchester, county of Suffolk, and State of Massachusetts,(whose post-office address is No. 13 Center Court, Dorchester, Massachusetts,) have invented an Improvement in Adjustable lVindow-ShadeFixtures, of which the following description, in connec tion with theaccompanying drawings, is a specification, like characters on thedrawings representing like parts.

This invention relates to window shades and particularly to adjustableroller window shades, and its object is to provide an improved form offixture for that type of shade that will possess several advantages oversuch fixtures as commonly constructed.

Referring to the drawing of a preferred form of my invention selectedfor illustration and description herein: Figure 1 is a Specification ofLetters Patent.

therefor used in connection with adjustable shades of this type havebeen designed and adapted for use, first; upon the outer or front faceof the window casing, or second; upon the inner edge thereof adjoiningthe sash, but they have not been designed for use in either position asdesired. This fact has resulted in great inconvenience and expense forthe reason that it has compelled a dealer to; keep in stock both kindsof fixtures for use as required. To avoid this inconvenience andexpense, I have invented the universal fixture illustrated herein andadapted to be used at will in either of above positions, and will nowproceed to describe the several members thereof and manner of using thesame.

The pulley brackets 2, 3, Fig. 1, are formed preferably by properlyfolding a blank 17, see Fig. 1, of suitable material, as metal. Thisblank having been first cut with the outline shown in Fig. 4: and aU-shaped aperture 18, the wing 19 is bent outwardly to the left, seeFigs. 2, 5, if the bracket is to be a right hand bracket, that is, to beused on the upper right hand corner of the easing, Fig. 1, and the wing19 is bent or folded in the opposite direction, or to the right, if thebracket is to be a left hand bracket, as if it is to be used at theupper left hand corner. It being, for instance, the intention to form aright hand bracket, Figs. 1 to 4:, the blank 17 is next folded along thedotted line 20 parallel with the wing 19, Fig. 5, next at right anglesthereto, again parallel with the wing 19 and finally to the left, Fig.5, in line with body of the blank. It is understood, of course, that thewords parallel and right angle are used in their common and generalsense and not to specify a mathematically exact mechanical construction,and the same is true when they are used hereafter. The depending tongue21 is next offset outwardly, Fig. 3, to the extent that it is desiredthe bracket shall be positioned from the frontface of the casing, if anoutside bracket, and the adjacent tongue 22, Figs. 2, 3, 5, is offsetoutwardly at right angles thereto, see Fig. 5, to the extent that 1t isdesired the bracket shall be positioned from the inner edge of thecasing, if the bracket is to be used as an inside bracket, on

the casing, see dotted position, Fig. 1. r

The wing 23, Fig. 4, is finally folded (Pitt down upon the upper edgesof the various folded portions of the blank as described, to form a top,Fig. 3, thus completing the socket to receive the upper end of one ofthe guide rods 6, 7. If the bracket is to be a left hand bracket, thatis, to be used at the upper left hand corner of the casing the severalfolding operations are performed in the reverse direction as illustrated.by dotted lines, Fig. 5. A pulley 24: is next mounted in the bracket bymeans of the holes 25 and the lower edge of the bracket, if a right handbracket, is offset somewhat, at 25?, Figs. 2, 3, to permit the cord 13to be received therein for a purpose to be subsequently described.

The guide rod supporting brackets 4t, 5, are alike and may beconstructed similarly to the brackets 2, 3, by suitably folding theblank 26, see Fig. 8, provided with a tongue 27. This blank is firstfolded at right angles to the tongue 27, next parallel to the tongue 27,again at right angles thereto parallel with the first fold, and the wing28 is then folded across the bottom edge of said folds, Fig. 6, to forma bottom, and the tongue 27 finally offset the same distance as tongues21, 22, completing the bracket which may, of course, be used at eitherfront face as an outside bracket or the inner edge of the casing as aninside bracket.

The roller brackets 39, may be conveniently stamped out of the samesheet material as the brackets, or of any other suitable material. Thebracket 8, is in the general form of a yoke, the two arms 2930, of whichare folded, see Fig. 10, to form a rod embracing portion adapted toslidably receive the rod 6. The nose 31 of the blank 8 is provided witha suitable slot 32 to receive the usual rectangular post or pin on oneend of a Hartshorn or other similar shade roller. The opposite bracket 9is formed by a similar folding operation in the opposite direction,Figs. 11, 12, the nose 31 in that case being provided with a suitableand preferably round hole 33 to engage the usual round post on theopposite end of the shade roller. Both brackets are provided withapertures 34 in the arms thereof to receive the ends of the usual cords12, 13, which may be secured thereto by a knot in the usual manner.

The manner of assembling the several members of the complete set is asfollows: The brackets 2, 3, are positioned on the easing as beforementioned, either as outside brackets on the outer face of the casing,1, full lines, or as inside brackets on the inner edge of the casing, asmay be desired, Fig. 1, dotted lines. The upper ends of the rods 6, 7,herein rectangular, ext are positioned in the brackets 2, 3, and thebrackets 1, 5, are then secured to the casing thus locking the lowerends of these rods in posi- .by dropping the rectangular tion. Owing tothe tops 23, of the pulley brackets and bottoms 28 of the guide rodbrackets, which act to prevent the guide rods from moving vertically insaid brackets, it is unnecessary to either head over the ends of therods 6, 7, or provide them with nuts or other fastening means as iscommonly done. The roller 10 of desired type, with its shade 11, is nextplaced in position by first inserting the round post of the roller inthe hole 33 of bracket 9, and next post of the roller into the slot 32-of the bracket 3, the shoulder 35 of said bracket serving to prevent thepost from jumping out from said slot under ordinary circun. stances. Thecords 12, 13, are next attached. to the brackets 8, 9, in the usualmanner by means of the holes 31, the cord 12 being carried over bothpulleys in the brackets 2, 3, and the cord 13 over the pulley in thebracket 3 only, the former cord being carried down outside bracket 3,and the latter cord carried down in the offset position 24 at the insideof the bracket, thus keeping the cords separate and preventing twistingthereof. The cord 13 is preferably conveniently secured to the cord 12at a suitable point between the bracket 3 and the bracket 5 and he endthereof secured to the cleat or other member 16. The shade 11 and itsroller 10 may now, by means of the cords 12, 13, conveniently beadjusted at any desired point etween the upper and lower ends of thewindow casing.

As fixtures of this type are commonly constructed at present when theguide rods used are round and the roller brackets rotatable thereon, itis necessary to provide the roller end posts or studs with heads to prevent lateral displacement of the brackets which would thus allow theroller to drop therefrom. This difliculty is avoided in some cases byproviding the round guide rods with a flange or web which preventsrotation of the roller brackets thereon while permitting them to slidevertically thereof and serves, when bent laterally to form flanges forattaching the rods to the casing by means of screws or tacks. Such rods,however, must be made especially for such use and are expensive andnecessitate nailing or securing the same at frequent intervals to thecasing thus unnecessarily marring the same. Even in such cases it issometimes deemed necessary to provide the roller posts or studs withheads to prevent an lateral movement of the roller; or as a substitutefor this construction the opposite roller brackets are sometimes securedby a brace and connecting rod which unites them and prevents rotationthereof about the round guide rods. Again, it has been common to mountthe roller studs or posts in blocks, which in turn are constructed totravel up and down the casing, at its inner edge, between parallelstrips secured to said casing. This construction is particularly clumsyand disfiguring.

My improved construction, as shown and described herein, eliminates allthe disad vantages referred to.

The rectangular guide rods may be of standard size, rods always kept instock, and therefore less expensive than when and if made to order, andthe roller brackets being formed to embrace the same, they of course,cannot be moved thereabout and they thus prevent lateral movement of theroller.

The roller brackets may, of course be used, like the guide rodsupporting brackets and pulley brackets with the rods 6, 7, either atthe face or inner edge of the casing at will.

One advantage of using the brackets and their cooperating rods with thecurtain and its roller inside or between the opposite edges of thewindow casing is that such use brings the curtain nearer the sash andthat consequently excludes more light from the room. If the brackets areused on the inner facing of the window casing, the curtain is removedfrom the sash a distance equal to the distance from the sash to theinner face of the casing plus the distance from said casing to theroller in its position at the outer ends of the brackets 8, 9. If thebrackets are positioned upon the opposite edges of the window casing,and substantially against the window sash, as shown in dotted lines Fig.l, the curtain will be positioned from the sash a distance equal to thedistance from the sash or, Fig. 3, from the member 21 to the rod 5 whichwill be positioned in the socket provided with a cover 23 plus thedistance from the rod to the aperture 33 of the bracket 9, thus bringingthe curtain much nearer to the window sash; In either case the rods 6, 7cooperate in the same manner with the brackets 2, 3, 4t and 5 not onlyto guide the roller when it is raised or lowered, but also to preventany lateral swinging of the roller or curtain and also to prevent anyswinging of the roller and ourtain toward or from the window sash, asthe ordinary curtain is apt to be swung by the wind if the window isopen.

In some cases, as in factories, store rooms or ofiices, where it isdesired simply to exclude the sun, it is sufficient to place the curtainfixtures and curtain on the inner facing of the window casing, as shownin Fig. 1; on the other hand, in dwellings and rooms where privacy isdesired, it is desirable to have the curtain positioned as close to thesash as possible and in that case the fixture described herein may beused with equal facility as described above.

Having described a preferred form of m inventi n which, however, maydoubtless be modified within the spirit thereof, I claim:

In an adjustable window shade fixture, a bracket provided with a pulleyand a socket to receive the upper end of the shade roller bracket guiderod, said bracket having offset tongues in planes substantially at rightangles to each other affording a means for attaching the bracket andthereby supporting the rod to the edge or to the inner face of thewindow casing.
